7.4.5.
Adjust both outer guide bearings. when satisfied that the adjustment is accurate, carefully turn the blade wheels by hand to see if the
blade snags or rubs at any point.
7.4.6.
readjust bearing(s) if necessary.

blade guide adjustment
7.5.1.
Disconnect the machine from the power supply. (Figure 24 shows the blade guard (69) removed for clarity. It is not necessary to
remove the blade guard to make the following adjustments).
7.5.2.
to adjust the blade guide loosen the bolt indicated in fig.24. and allow the single bearing which runs on the back of the blade to rest
on the blade without exerting any pressure.
7.5.3.
rotate the blade guide (as shown in fig.24) until blade is perpendicular to machine bed.
7.5.4.
retighten the hex bolt ensuring that no pressure is applied to the back of the blade.
7.5.5.
Adjust the second blade guide in the same manner.
7.6.
cutting feed pressure
7.6.1.
the weight of the cutting arm itself applies pressure to the cutting blade and therefore to the workpiece. An adjustable spring is
attached to the arm and as the spring pressure is increased the cutting pressure is decreased.
7.6.2.
if the saw is making crooked or rough cuts or overheating is occurring it may be necessary to decrease the feed pressure by turning
the chromed adjusting rod in a clockwise direction as shown in fig.25.
7.6.3.
if the saw blade becomes dull quickly it may be necessary to increase the feed pressure by turning the chromed adjusting rod in an
anticlockwise direction as shown in fig.7.
